C]Criteva

If we just met in person, hello.

I’m David Leung.

I build beautiful, useful things for learning.

I was a teacher before I became a founder.

I taught programming, STEM and English in Hong Kong. That classroom experience still shapes every product I build.

Denmark taught me to explore. Hong Kong taught me to deliver. Today I run Criteva, a small education technology practice.
